Even without knowing a thing about programming, its easy to understand this is a big deal: Apples current language of choice, Objective-C, has been in the mix for Macs since the launch of OS X, and for iPhones and iPads from day one. For Apple to throw out the developer playbook across its entire product portfolio suggests there’s a big change afoot — and many devs aren’t sad to see it happen. [Objective-C’s] a real pain, says Alex Chung, the co-founder of Giphy, who has created multiple iOS apps. Swift is trying to borrow the best elements of moderately newer popular languages like Python and Javascript.
